Centralized Capacity Information Map

The Centralized Capacity Information Map (CCIM) is an online tool created by the Ontario Energy Board (OEB) that provides a high-level view of available capacity across Ontario’s electricity distribution systems. The CCIM displays information on electrical grid capacity for both customer load connections and Distributed Energy Resource (DER) hosting, helping support informed planning and the delivery of affordable, reliable, and clean energy.

The CCIM is intended for preliminary screening only and does not replace any formal connection impact assessment process required by Wasaga Distribution.

Centralized Capacity Information Map FAQs

The CCIM is an online tool created by the OEB to give users a high-level view of where there’s available capacityon Ontario’s electricity distribution systems. In simple terms, it helps users see two main things:

Available load capacity: The ability to serve new or expanded electricity demand.
Available hosting capacity for DERs: The ability to connect new projects like solar panels, wind turbines, or battery storage

The CCIM is a planning aid, designed for early-stage screening. Users can use the tool to quickly check which areas might be suitable for their project before contacting a distributor. The map shows capacity in broad ranges and reflects system conditions at the time distributors submitted their data. It’s not a substitute for detailed assessments, as conditions can change and every project has unique requirements.

The Available Load Capacity map environment shows areas of the electricity distribution system that can accommodate new customer loads, such as housing developments, commercial buildings, or industrial facilities, without requiring major system upgrades. This helps businesses and developers identify locations where connecting new demand is likely to be simpler and faster.

The Available DER Hosting Capacity map environment focuses on the ability of the grid to integrate DERs like solar panels, battery storage or other generation facilities. It highlights where the system is expected to be able to host additional generation facilities. It highlights where the system is expected to be able to host additional generation without causing reliability or safety issues. Data is provided for a range of typical project types, such as inverter or non-inverter-based installations, as well as for projects designed only to displace a customer’s load rather than inject power.

Both map environments are intended for preliminary screening only and do not replace any formal connection application or Connection Impact Assessment (CIA) process. They provide early insights to help users plan projects and reduce uncertainty before engaging in detailed engineering studies.

The CCIM is designed for anyone planning electricity-related projects in Ontario. Key stakeholders include:

Project developers and businesses looking to identify areas where new or expanded electricity demand can be connected easily.
Renewable energy and DER developers assessing where solar, wind, or battery projects can be hosted without major grid upgrades.
Municipal planners and consultants seeking high-level capacity insights for community growth or electrification strategies.
Large energy consumers evaluating suitable locations for new facilities.

The CCIM provides early-stage screening to reduce uncertainty before engaging distributors for detailed assessments.
